3 Claims. (Cl. 137-604) My invention relates to mixing and more particularly to the mixing of liquids for use as a fuel mixture for engines and the like, this application being a continuationin-part of my application Serial No. 691,893, filed October 23, 1957, now Patent Number 3,003,521.

One of the objects of my invention is to provide mixing apparatus which is so constructed and arranged that a liquid contained therein may be metered and proportionally mixed with another liquid flowing through said apparatus.

Another object of my invention is to provide apparatus of the foregoing described character which is equipped with adjustable metering means whereby a pre-established ratio between the liquids may be maintained even though a change is obtained in the viscosity of one of the liquids.

A further object of my invention is to provide apparatus of the foregoing described character equipped with temperature responsive means for denoting the viscosity of one of the liquids whereby the metering means may be adjusted to accord with a change in the viscosity to thus maintain a pre-established ratio between the liquids being mixed.

An important object of my invention is to provide apparatus of the foregoing described character which is portable and simple in construction, durable in use, efficient in operation, economical in manufacture, and lends itself to the mixing of various liquids in predetermined proportions with a minimum of initial adjustment to obtain said proportions.

With the above and other objects in view, as will hereinafter appear, the invention consists in the combination and arrangement of parts hereinafter set forth and illustrated in the accompanying drawings from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

Referring to the drawings wherein like reference characters designate like parts throughout the several views:

FIGURE 1 is a side elevation, partly in section, of my invention;

FIGURE 2 is a top plan view thereof;

FIGURE 3 is a detail sectional view taken on the line 33 of FIGURE 1; and

FIGURE 4 is a detail vertical sectional view taken on the line 4-4 of FIGURE 2.

In practicing my invention, as illustrated in the drawings, I provide a receptacle having a chamber 11 constituting a reservoir for containing a mixing liquid, for instance, lubricating oil 12 which is introduced into the chamber 11 through a filling spout 13 provided with a vented removable cap 14. The receptacle has extending therethrough a fuel supply conduit or pipe 15 for supplying a fuel mixture to a gasoline engine or the like. The upper end 16 of the conduit extends above the top wall 17 of the receptacle and is provided with a resilient coupling 18 having a tapered bore for receiving and tightly retaining therein the outlet end of a discharge nozzle 19 provided on the end of a hose leading from a gasoline supply pump or the like. The coupling is disposed within an elongated metallic collar 20 fixed to the top wall 17 of the receptacle. A bar 21 or the like constituting a handle is connected to and extends between the spout 13 and collar 20 whereby the receptacle may be conveniently supported during operation of the apparatus.

The lower end 22 of the conduit 15 extends through the side wall 23 of the receptacle adjacent the bottom wall 24 and is connected to a flexible armored tubular member or hose 25 leading to the gasoline tank of an engine. Above the top wall 17 the conduit 15 is provided with a constriction 26 constituting a Venturi nozzle in which is connected the upper end 27 of an aspiratory tube 28 extending downwardly within the reservoir and terminating in an intake port 29 in proximity to the bottom of the reservoir. The intake port 29 is defined by a collar 30 carried by the tube 28 and cooperates with a disc 31 having a plurality of openings 32 of varying diameters formed therein for selective registration with the intake port 29 whereby the amount of oil fiowing through said port 29 may be controlled in accord with its viscosity.

The disc 31 is fixed to the lower end of a rotatable spindle 33 having an upper end journaled through the top wall 17 of the receptacle and provided with an operating knob 34. The lower end section of the spindle is journaled in a bearing bracket 35 carried by the lower end of the tube 28 and with the spindle having fixed thereon a sleeve 36 superjacent the bracket 35 and on which spindle a coil spring is mounted, between the bracket and sleeve, for maintaining the disc 31 in tension engagement with the collar 30 to preclude rotation of the disc except through the instrumentality of the knob 34.

A scale-plate 37 is secured to the top wall 17 below the knob 34 and through which plate the upper end of the spindle 33 extends. The. knob 34 is provided with a pointer 38 which cooperates with indicia or markings 39 in the nature of symbols on the plate 37 for denoting the positions of the various openings 32 in the disc 31 relative to the intake port 29 whereby an opening 32 of a desired size may be selectively positioned in communication with the intake port 29 and thus control the flow of oil from the reservoir into the tube 15 by the siphoning action created by the flow of gasoline through said tube 15 in supplying the tank of the engine with gasoline from the gasoline pump. A thermometer 40 extends downwardly into the reservoir and is equipped with a scale 41 carried on the top wall 17 and containing a plurality of symbols which indicate the temperature and, accordingly, the viscosity of the oil 12 contained within the reservoir, it being understood that the viscosity of the oil is directly related to the temperature thereof.

The symbols on the plate 37 associated with the valve correspond with the symbols on the temperature dial 41 so that by adjusting the spindle 33, through the medium of the knob 34, a reading on the plate 37 may be obtained which coincides with the reading on the scale 41 whereby an opening 32 of proper size is disposed in registration with the inlet port 29 thereby permitting oil in the reservoir to be withdrawn through the tube at a rate for mixing with the gasoline in accord with a pre-established proportion. Obviously, upon a change in the viscosity of the oil, as indicated by the thermometer reading, the spindle is operated to effect registry of another of the openings 32 with the inlet port 29 to compensate for the change in the viscosity.

In use, assuming the disc 31 is in position to effect registry of the inlet port with a suitable opening 32 to accord with the viscosity of the oil, as indicated on the plate 37, a flow of gasoline is effected from the pump downwardly through the tube 15 and thus siphons a predetermined amount of oil from the reservoir by virtue of the Venturi nozzle 26, whereby a designed mixture of gasoline and oil is obtained and introduced into the tank of the engine, through the hose 25, as a fuel for the engine. Obviously my invention provides means by which gasoline and oil may be readily mixed in proper proportions as a fuel mixture and said proportions capable of being maintained upon a variation in the viscosity of the oil.

Without further elaboration, the foregoing will so fully explain the invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service. Moreover, it is not indispensable that all the features of the invention be used conjointly since they may be employed advantageously in various combinations and sub-combinations.

It is obvious that the invention is not confined solely to the use herein disclosed in connection therewith as it may be utilized for any purpose to which it is adaptable. It is, herefore, to be understood that the invention is not limited to the specific construction as illustrated and described, as the same is only illustrative of the principles involved which are capable of extended application in various forms, and the invention comprehends all construction within the scope of the appended claims.
